To all whom z't 7.22.6142/ concern Beit known that l, Louis SoHo'r'r, acitizen of the United States of America, `and a resident of Cincinnati.in the county oi `l`l'amilton and State of Ohio, have invented new anduseful Improvements in Riveting J igs, of which the following is aYspecifica` tion.

An object of my inventionis to provide a riveting for use in mountinghandle brackets and the like upon vessels such as sheet iron wash tubsand pails.

Another object is to provide a device ot this kind which is simple ofconstruction and operation. Y

Another object is to provide a device of this kind, the use of whichwill effect a considerable saving of time and labor.

vThese and other objects are attained by the means described herein anddisclosed in the accompanying drawing, in which: Fig. 1 is a sideelevation of a vessel having a device of my invention mounted thereonfor retaining the handle brackets and rivets in position for riveting.

Fig. 2 is a cross sectional view taken on line 2-2 of Fig. 1.

Fig. 3 is a cross sectional view taken on line 3-3 of Fig. 1.

Fig. 4 is a fragmental elevation of a vessel showing the brackets andhandle structure.

The device comprises an anvil plate G, which is in practicegiven aslightly curved or arcuate working surface to accommodate thev inside ofthe wall 7 of a vessel 8 upon which handle brackets 9 are to be mounted.An L-shaped block 1'0 is secured centrally at one end of the anvil plate6 by means of machine bolts 11 or by any other suitable means. The block10 has a ange 12 which extends parallel to the anvil plate 6 and inspaced relation thereto so that the rounded rim or lip 13 of the vesselwall 7 may be accommodated between the anvil plate and said flange. Apair of spaced arms 14 extend from the flange 12 in alignment therewithand are provided with aligned transverse bores 15. A clamping block 16having a suitable handle rod 17, is pivotally mounted upon rod 18 whichextends through the aligned bores 15 in the arms 14. Suitable pins orlugs 19 extend outwardly from the anvil plate 6 and are adapted toengage the top of the rim 13 of the vessel 8. Thus the jig is placedupon the wall 7 ofthe vessel with the anvil Plate upon the inner Side ef1924. Serial No. 711,908.

the wall and the flange 12 andfarms 1l.

.the clamping block 16 is positioned eccentric to the rod 18 so thatwhen the clamping vblock 1.6 is in the position shown in dottedy lieve0.11 2th@ rim and wall ,of the vessel lmay be passed between said ,claiaiping block and the anvil plate. When the Eclan'iping block isturned by means of handle l17 on its eccentric axis the face 2O of theblock 16 will engage the outer wall of the vessel. By bringing thehandle 17 substantially parallel with the wall 7 of the vessel the jigwill be tightly clamped upon said wall. The vessel wall in practice, isprovided with rivet holes 21 in which rivets 22 are inserted after whichthe jig is placed in position in engagement with the heads 23 of all ofthe rivets required to secure a pair of the handle brackets 9 upon thevessel. The clamping block 16 is then actuated totightly clampl the jigupon the vessel wall and the rivet heads at which time the handlebrackets 9 may be placed in position and thevriveting operationperformed. It should be noted that a plurality of rivets may be insertedin the various rivet holes and may be held securely in position so thatthe workman may with great efliciency and rapidity perform the necessaryriveting operations without having to direct his attention to positionthe rivet as each one is headed. Having riveted a pair of the handlebrackets 9 to the wall of a vessel the handle is'readily affixed byinserting a handle 24 between the brackets 9 and inserting asuitablefrod 25 through the aligned perforations 26 in the brackets 9after which the ends 27 of the rod 25 may be spread or riveted.

What I claim is: 1 Y

1. In a device of the class described the combination with an anvilplate for engaging the inner sider of a vessel wall, of a pair of spacedarms mounted in spaced relation to the anvil plate, and a clampingmembermounted eccentrically between the arms for engaging the outer side yofsaid vessel wall.

2. In a device of the class described the combination with an anvilplate having a convex riveting: surface, a block mounted upon saidriveting surface, a flange extending from the block in spaced relationto the anvil plate, spaced arms extending Jfrom loo and invalignmentwith said flange said arms clamping member having a perforation entending therethrough and positioned eccentrioally to the clamping facethereof, a rod extending through the aligned perforations in the armsand through the perforation in the clamping block for mounting theclamping block pivotally and eccentrioally between said arms, and meanscarried b v the block for moving said block about its eccentrie mountinginto and out of engagement with the anvil plate.

3. In a device of the Class described the combination with an anvilplate for engaging the inside of a vessel Wall, a pair of lugs extendingfrom the anvil plate for engaging the top edge of said vessel Wall ablock mounted on the anvil plate, a fiange extending from the block inspaced relation to the anvil plate and the outside of the vessel Wall.and an eccentrically mounted clamping block pivotallv mounted on theflange for engaging the outside of the vessel Wall.

el. ln a riveting jig the combination With an anvil plate for receivinga vessel wall having rivets extending therethrough, lugs extending fromthe anvil plate for engaging the top of the vessel Wall whereby theanvil plate is suspended in position over the rivets, a flanged blockextending about the top and outside of the vessel Wall, and clampingmeans mounted on the block for engaging the outside of the vessel Wallivhereb)7 rivets are securely held in position in rivet holes in thevessel Wall.

Intestimonv whereof, I have hereunto subscribed my name this 30th day ofApril` 1924.
